I have mixed feelings about this one. Sound quality is good, I felt no wow effect but still I was pleased after the calibration.
What is bad is the Garmin support, I had no issues with other by headphones but with nura they give me choppy and breaking sound. Nura support told me to ask Garmin to change the codecs in the watch haha.
